Embodiment Construction

[0010] first reference figure 1 , which shows in block diagram form an ultrasound system constructed in accordance with the principles of the present invention. A transducer array 10a for transmitting ultrasonic waves and receiving echo signals is provided. In this example, the array shown is a two-dimensional array of transducer elements capable of providing 3D image information, but implementations of the invention may also employ swept one-dimensional arrays of transducer elements , which will generate a 2D (planar) image from volume regions. The transducer array is coupled to a microbeamformer 12a, which controls the transmission and reception of signals by the array elements. The microbeamformer is also capable of performing, at least in part, the grouping or " Beamforming of signals received by "patches". The micro beamformer 12a is coupled to a transmit / receive (T / R) switch 16, which switches between transmit and receive and protects the main beamformer 20 from high...

Abstract

An ultrasonic diagnostic imaging system produces 3D images of blood flow which depict both the location of blood pools and flow velocity in one image. B mode data is acquired over a volumetric region and inverted to a range of grayscale value which highlights anechoic regions relative to regions of strong echo returns. Flow data is acquired over the same volumetric region and both data sets are volume rendered. The two volume renderings are then merged into a single 3D image in which the B mode pixel values are tinted in accordance with flow at the pixel locations.

Description

technical field [0001] The present invention relates to medical diagnostic ultrasound systems, and more particularly, to ultrasound systems that perform three-dimensional (3D) color flow imaging. Background technique [0002] In ultrasound diagnostic imaging, it is a common practice to employ 3D volume rendering imaging to visualize the inner surfaces of human structures such as the ventricles of the fetal heart. The dynamics of the fetal heart rate can be captured as a series of volumes using a 3D data acquisition technique known as Spatio-Temporal Image Correlation (STIC), where each volume can be captured as a Cineloop consisting of successive image frames. It is also common practice to capture a 3D volume composed of color flow data and employ various 3D volume rendering techniques to form 2D image projections of this data volume. Afterwards, the 3D color flow data can be visualized as a cross-sectional plane, or visualized as a 3D image using various 3D rendering meth...
